Gasoline is extremely flammable and explosive under
certain conditions.
* EFI components are under high pressure. Verify
system pressure has been relieved before disassembly.

Gasoline powered engine exhaust fumes are poisonous
and can cause loss of consciousness and death in a
short time.

SERVICE NOTES
• For more convenient and accurate testing of EFI components,
it is recommended dealers utilize the KWP Diagnostic Tool
Software (dealer only), or testing may be done manually using
• There had 80% problems of all EFI problems caused by
wiring harness connections.
• Never attempt to service any fuel system component while
engine is running or ignition switch is "on."
• Cleanliness is essential and must be maintained at all times
when servicing or working on the EFI system. Dirt, even in
small quantities, can cause significant problems.
• Do not use compressed air if the system is open. Cover any
parts removed and wrap any open joints with plastic if they
will remain open for any length of time. New parts should be
removed from their protective packaging just prior to
installation.
• Clean any connector before opening to prevent dirt from
entering the system.
• Although every precaution has been taken to prevent water
intrusion failure, avoid direct water or spray contact with
system components.
• Do not disconnect or reconnect the wiring harness connector
to the control unit or any individual components with the
ignition "on." This can send a damaging voltage spike through
the ECU.
• Do not allow the battery cables to touch opposing terminals.
When connecting battery cables attach the positive (red) cable
to positive (+) battery terminal first, followed by negative
(black) cable to negative (-) battery terminal.
• Never start the engine when the cables are loose or poorly
connected to the battery terminals.
• Never disconnect battery while engine is running.
• Never use a battery boost-pack to start the engine.
• Do not charge battery with key switch "on."
• Always disconnect negative (-) battery cable lead before
charging battery.
• Always unplug ECU from the wire harness before
performing any welding on the unit.
